So, just got the car back aft its third visit to the dealer in just over a week. They had to borrow "tool" from a Citroen dealer nearby, as they couldn't find another Peugeot dealer that had one.
Apparently, they plug the tool into the Sat Nav, park it up outside with the engine running for 20 minutes, and the "tool" tells them if there are any faults.
They tell me that I need a new GPS aerial, and so have had to order one in, so guess what?, it has to go back in a fourth time once this arrives.
Although this is the part I suspected from the start, I am still sceptical that this will resolve my issues.
Btw, Sat Nav worked fine all the way back from dealership, but I stopped for fuel on the way home, when I started the car, the screen took @ 10 seconds to flip open, then it was blank for @ 20 seconds, then Peugeot logo for 20 seconds, then worked OK again.
Just a bit concerned what they will say when they go to replace my GPS aerial & they see the wires I have routed for my dash cams.
On the plus side, they tell me they have fixed my screen wash leak & my new tyres look nice
